CNC machining center, carving and milling machine, engraving machine, the difference between these three?


Machining center, engraving and milling machine, engraving machine, what is the difference between them? I believe this sentence many friends who have just joined the circle will ask, and then not quite understand when buying machinery and equipment, do not know how to distinguish, in the end, what kind of equipment should be bought to meet their needs, today I will share the difference between the three.

Carving and milling machine.

As the name implies is that you can carve, can also be milled, on the basis of the carving machine increased spindle, servo motor power, the bed to withstand the force, while also maintaining the high speed of the spindle. Engraving and milling machine also to high-speed development, generally known as high-speed machine, cutting ability is stronger, processing accuracy is very high, but also can be directly processed in the hardness of the material above HRC60, a molding, widely used in precision mold die die rough finishing processing once completed, mold copper electrodes, aluminum products batch processing, shoe mold manufacturing, jig processing, watch eye realm industry. Due to the high cost performance, fast processing speed, processing products with good finish, in the machine tool processing industry increasingly occupies an important position.

CNC machining center.

Hong Kong and Taiwan, Guangdong, also known as computer gongs, in the machining center on the processing of parts is characterized by: the machined parts after a clamping, CNC system can control the machine according to different processes automatically select and replace the tool; automatically change the machine spindle speed, feed and tool relative to the workpiece trajectory and other auxiliary functions, continuous to the workpiece surface automatically drilling, countersinking, reaming, boring The machining center can automatically change the machine spindle speed, feed and tool trajectory relative to the workpiece and other auxiliary functions.

Since the machining center can complete multiple processes centrally and automatically, it avoids human operation errors, reduces workpiece clamping, measuring and machine tool adjustment time and workpiece turnover, handling and storage time, and greatly improves processing efficiency and processing accuracy, so it has good economic benefits. Machining centers can be divided into vertical machining centers and horizontal machining centers according to the position of the spindle in space.

Engraving machine.

Torque is relatively small, high spindle speed for small tool processing, focusing on the "carving" function, less suitable for strong cutting of large workpieces. Most of the products on the market under the banner of engraving machine are mainly for processing crafts, low cost, due to the low precision, not suitable for mold development; engraving and milling machines, machining centers. Engraving machine indicators data aspects of comparison spindle maximum speed (r / min): machining center 8000; carving and milling machine most common 240,000, high-speed machine minimum 30,000; engraving machine is generally the same as the carving and milling machine, for high light processing engraving machine can reach 80,000, but that used not the general electric spindle but air-floating spindle.

Spindle power: machining center is the largest, from a few kilowatts to tens of kilowatts are available; carving and milling machine is the second, generally within ten kilowatts; engraving machine is the smallest.

Cutting volume: machining center is the largest, especially suitable for heavy cutting, open coarse; engraving and milling machine is the second, suitable for finishing; engraving machine is the smallest.

Speed: As the engraving and milling machine and engraving machine are relatively light, their moving speed and feed speed than the machining center, especially equipped with linear motor high-speed machine moving speed of up to 120m / min.

Accuracy: The accuracy of the three is about the same.

In terms of processing size.

Table area can be a better response to this. Domestic machining center (computer gong) the smallest table area (unit mm, the same below) in 830 * 500 (850 machine); carving and milling machine the largest table area in 700 * 620 (750 machine), the smallest is 450 * 450 (400 machine); engraving machine generally does not exceed 450 * 450, common is 45 * 270 (250 machine).

In terms of application objects.

Machining center for the completion of a larger milling volume of workpiece processing equipment, large molds, hardness of harder materials, but also suitable for ordinary mold opening coarse; engraving and milling machine for the completion of smaller milling volume, small mold finishing, suitable for copper work, graphite and other processing; low-end engraving machine is biased towards wood, two-color plate, acrylic plate and other hardness is not high plate processing, high-end suitable for wafer, metal shell and other polishing Grinding.

In foreign countries there is no engraving and milling machine term (CNC engraving milling machine), strictly speaking, carving is part of the milling, so foreign countries only the concept of machining centers, and the concept of small machining centers derived from this to replace the engraving and milling machine. Purchase engraving machine or purchase CNC milling machining center is often a question to ask yourself, depending on the actual production needs. In addition, there are currently prevalent high-speed cutting machine tools (HSCMACHINE), the country is called high-speed machine.

Or let us first figure out the three model differences.

1, CNC milling and machining center used to complete the larger milling volume of the workpiece processing equipment.

2, CNC engraving and milling machine used to complete a smaller milling volume, or soft metal processing equipment.

3, high-speed cutting machine tools used to complete the medium milling volume, and the milling after the grinding volume to minimize the processing equipment.

4, in-depth analysis of the above equipment structure and data processing type can help us make the right choice. The article has been very detailed about the difference between the engraving and milling machine and machining center and engraving machine, I believe we should have a certain understanding of these three in mind.
